My 13 year old son is worried about his nipples, a while ago they started hurting when he was in the swimming pool, and began to be painful when bumped or pressed, that continued for quite a while and he did not like it.
A while later they wont hurting anymore but his nipple was big and kind of puffy and is still like that today, its been about a year since this started, should we be concerned? He doesn't like it and is even embarrassed to take his shirt off now.
